Manage UCP quotes and checkout sessions over MCP

Discover a UCP profile, price a cart and manage checkout sessions through MCP; payment completion is not yet available.

The API reference for the UCP quote, which the new get_ucp_quote tool calls.

The UCP tools cover discovery, quotes and checkout-session management.

  • Read the public business profile and request a cart quote.
  • Create, list, read, update or cancel checkout sessions with the appropriate access.
  • Send idempotency_key when creating a session. A retry with the same request returns the existing session; a changed request using that key is refused.

complete_ucp_checkout returns payment_not_configured with status 501. It does not charge a buyer, complete the session or create an order.
